A vaporizer includes an outer tube configured to receive a flow of heated gas and an inner tube disposed at least partially within the outer tube. The inner tube is spaced apart from the outer tube such that the flow of heated gas is channeled through an annular space therebetween. The vaporizer also includes a crucible disposed at least partially within the inner tube. The crucible is extendable and retractable relative to the inner tube and within the outer tube. The crucible is configured to hold a molten metal such that a surface area of the molten metal exposed to the flow of heated gas is adjustable based on the position of the crucible relative to the inner tube. A heater is configured to vaporize the molten material and the vapor mixes with the flow of heated gas.

The invention relates to a nuclear reactor operating according to the dual fluid principle with a special liquid metal fissionable mixture as liquid fuel in the liquid fuel line, which has a high percentage of actinoids, preferably 69% and higher. Preferred metals are selected from chromium (Cr), manganese (Mn) and iron (Fe). Preferred actinoids are selected from thorium (Th), uranium (U) and plutonium (Pu). The mixtures and resulting multicomponent alloys need not necessarily be an eutectic.

A nuclear reactor comprising: a moderator including a metal hydride; and a nuclear fuel in which europium is added as an additive to a main nuclear fuel material. Thus, the nuclear reactor can be kept in the subcritical state even under the state where all the control devices are pulled out before startup.

Some embodiments include an chemical separation mechanism for a molten salt reactor where the molten salt may include fission products. In some embodiments, the chemical separation mechanism includes a molten salt receptacle with a molten salt disposed within, a solvent receptacle having a solvent disposed within; an electrode; and an electrode mechanism. In some embodiments, the electrode mechanism may be configured to submerse the electrode into the molten salt receptacle such that a chemical reaction occurs between the electrode and one or more of the fission products in the molten salt. In some embodiments, the electrode mechanism may submerse the electrode into the solvent receptacle such that a chemical reaction occurs resulting in one or more of the fission products being deposited into the solvent.
